The volatile organic compounds generated from the Maillard reaction between l-ascorbic acid and l-cysteine in hot compressed water.

Background: Hot compressed water (HCW), also known as subcritical water (SCW), refers to high-temperature compressed water in a special physical and chemical state. It is an emerging technology for natural product extraction. The volatile organic compounds (VOCs) generated from the Maillard reaction between l-ascorbic acid (ASA) and l-cysteine (Cys) have attracted significant interest in the flavor and fragrance industry.

Gut microbiota from essential tremor patients aggravates tremors in mice.

Background And Objective: Essential tremor (ET) lacks effective treatments because its underlying mechanism is largely unknown, but may involve gut microbiota via the microbiome-gut-brain axis. We explored the effects of gut microbiota on ET in mice.

Methods: Specific pathogen-free C57BL/6J mice were gavaged with stools from ET patients or matched healthy individuals.

Correlations between flavor and fermentation days and changes in quality-related physiochemical characteristics of fermented Aurantii Fructus.

The effects of different fermentation times (0, 1, 2, 3, 4, and 5 days) on the physicochemical properties and flavor components of fermented Aurantii Fructus (FAF) were evaluated. Component analysis identified 66 compounds in positive ion mode and 32 compounds in negative ion mode. Flash GC e-nose results showed that propanal, (+)-limonene and n-nonanal may be the flavor characteristic components that distinguish FAF with different fermentation days.

Kinetics of -ascorbic acid degradation and non-enzymatic browning development in hot-compressed water.

The effect of reaction conditions, which comprised the reaction temperature (150-190°C), processing time (0.50, 0.75, 1.

Washed microbiota transplantation improves patients with metabolic syndrome in South China.

Background: Metabolic syndrome (MS) is a growing public health problem worldwide. The clinical impact of fecal microbiota transplantation (FMT) from healthy donors in MS patients is unclear, especially in southern Chinese populations. This study aimed to investigate the effect of washed microbiota transplantation (WMT) in MS patients in southern China.

Long-term efficacy and safety of cap-assisted endoscopic sclerotherapy with long injection needle for internal hemorrhoids.

Background: Hemorrhoids are a common anal condition and can afflict an individual at any age. Epidemiological survey results in China show that the prevalence of anorectal diseases is as high as 50.1% among which 98.

Washed microbiota transplantation improves patients with high blood glucose in South China.

Background And Aims: Although fecal microbiota transplantation (FMT) from healthy donors has been shown to have hypoglycemic effects in animal models of diabetes, its clinical impact in patients with abnormal blood glucose metabolism is unclear, especially in southern Chinese populations. The aim of this study was to investigate the feasibility and efficacy of washed microbiota transplantation (WMT) in the treatment of abnormal blood glucose metabolism in a population in southern China.

Methods: The clinical data of patients with different indications who received 1-3 treatments of WMT were retrospectively collected.

Selective determination of trace 17β-estradiol in dairy and meat samples by molecularly imprinted solid-phase extraction and HPLC.

Molecularly imprinted solid-phase extraction (MISPE) combined with HPLC were used to detect trace 17β-estradiol (E2) in different dairy and meat samples. E2 imprinted mono-dispersed microspheres prepared by modified precipitation polymerisation method were used as MISPE sorbents. Under optimum MISPE and HPLC conditions, trace (0.

Molecularly imprinted polymer microspheres enhanced biodegradation of bisphenol A by acclimated activated sludge.

The impacts of bisphenol A- imprinted polymeric microspheres (MIPMs) on the biodegradation of bisphenol A by acclimated activated sludge were studied. Due to the selective adsorption of MIPMs to bisphenol A (BPA) and its analogues, addition of MIPMs to activated sludge increased levels of BPA and its metabolites, which were also the substrates of biodegradation. Higher substrates (BPA and its metabolites) level promoted biodegradation efficiencies of activated sludge via accelerating removal speed of BPA and its metabolites, increasing degradation rate and decreasing half-lives of biodegradation.
